Considering the physical prowess that Liverpool striker Mario Balotelli, 24, can brag, it is almost an anomaly when he becomes bullied out of a game by a merciless centre back.

When the Reds hosted Aston Villa at Anfield on Saturday afternoon, though, that is precisely what happened as Swiss defender Philippe Senderos emerged on top of their personal duel.

During the game, Senderos was regarded as a pillar of strength, however, with the benefit of scrutiny over slow-motion replays, the cleanliness of the Villain's defensive work came under question as he appeared to kick out at the Italian.

Responding in the Birmingham Mail, Senderos explained that such incidents were part and parcel of a defender's job: "It's things that happen on the pitch," he said.

"We're running towards each other, against each other, but there's no harm in going like this."

He continued: "I'm trying to do my job. Everyone is running towards each other, kicking each other.
